and as here shownpreferably consisting of a receptacle whose walls lare formed of vitreous or other suitable material. The bottom of the receptacle is preferably formed with a metallic plate 2 and the top of the receptacle is closed by means of a metallic flanged cover 3 resting in the shouldered annular portion 4 of the upper end of the walls 1. Suspended within the receptacle is a sheet iron bell 5 provided at its top with suitable handles 5" forhandling the receptacle when placing it into and out of position and with a vent 6 in its top to permit of its removal. The lower end of the bell 5 projects into the water 7 located in the main receptacle and forming a water seal between the sides of the receptacle and the bell. The bell 5 is held in avertical position by means of angle'iron brackets 8 on the sides of the receptacle against which the sides of the bell bear. Loosely resting on the bottom of the receptacle is a sheet metal support having tapering sides 9 resting on the bottom of the receptacle and having an annular upper end 10 which extends about metallic vertical strips 11. An annular metallic band 12 is riveted to the inner side of the vertical strips 11 and is located opposite the annular portion of thel metallic lsupport and the said annular portion 10 projecting up beneath the lower end of the bella It will be seen that by means of this construction a strong support is provided for the vertical strips 11 and the gas will be directed from the inside of the metallic support having tapering sides 9 to the inside of the bell and prevent the gas escaping from beneath the lower edge of the bell or breaking the water seal.

Mounted inthe upper end of the bell is a carbid receptacle 13 of a hopper shape and provided with a flanged cover 14 which fits over an annular metallic band 15 secured to the upper ends of the verticall strips 11 and to the upper rim of the hopper 13. A conical shaped shield 16, located a short distance above the mouth of the hopper 13 and mounted on the lower end of a rod 17 secured at its upper end to the cover 14 of the hopper 13, serves as a guide to direct the carbid toward the discharge end of the hopper, and at the same time prevents it from clogging the same. The nozzle end 18 of the hopper is secured to a disk plate 19 mounted on the lower end of a tube 20 which is formed at its upper end with a shouldered enlarged portion 21 which is seated in fixed position on the top of the cover 14.

Mounted on the under side of the plate 19 and in alincment with the nozzle 18 of the hopper is a tapering spout 22 for the passage of the carbid` A number of tilting carbid chutes 23 open at each end a-re mounted on rods or arms 24 projecting radially from a hub 25 secured to a reduced lower end portion 26 of a shaft 27 projecting up through the tube 20. As shown in Figs. 1 and 2 the position of the chutes on the rods 24 is such that as the shaft 27 rotates the chutes 23 are carried about beneath the plate 19 and beneath the tapering spout 22. Each of the chutes 23 is hinged at one end to a rod 24 and each chute 23 has its rear portion formed with the upwardly inclined extension 28 which as thev chutes are carried about beneath the plate 19 ride against the under side of the latter and hold the chutes 23 in a horizontal position as shown.

In order that the chutes may deliver the carbid as they receive it from the hopper in passing beneath the spout 22, a suitable means is provided for releasing the chute to permit it to tilt and discharge the carbid and as here shown said means preferably consists in forming the plate 19 with an upwardly curved portion 29 which when a chute passes beneath the same, permits the extension 28 of the chute to ride against,

the under side of the upwardly curved portion 29 which being formed with two inclines permits the chute to tilt and dump the carbid into the water as shown in Fig. 1, and as the extension 28 reaches the lower end of the opposite incline the chute is moved to its normal horizontal position. In order to rotate the shaft 27 to cause this operation of the chutes, a toothed gear wheel 30 is loosely mounted on the upper shouldered end of the tube 20. Secured to the upper end of the shaft 27 is a circular head 3l which is spaced from the head of the toothed wheel 30 and rests upon ball bearings consisting of balls 32 located in raceways in the head 31 and in the hub of the wheel 30.

Mounted in any suitable manner in the hub 31 are a number of pawls 33 which are adapted to engage in one direction of the movement of the toothed wheel 30 notches 34 in the upper side of the wheel 30 and to ride over said notches in the opposite movement of said wheel. Meshing with the wheel 30 is a rack bar 35 which is pivotally connected at one end to an arm 36 secured at its upper end to a two-armed lever 37 pivotally mounted on the upper end of an upright 37. Mounted on one end of said double armed lever 37 is a counterweight 38 and on its other end is a friction wheel 39 which bears against the under side of the top of the bell 5. By means of this construction and arrangement7 as hereinbefore described, as the bell 5 rises by the increase of pressure of the generated gas, the end of the lever 37 on which the wheel 39 is mounted is permitted to rise being elevated by the counterweight 38, and the arm 36 is swung thereby so as to push forward the racl bar 35 which rotates the beveled wheel 30, the notches 34 in the wheel 30 slipping past the pawls 33 and thereby imparting no motion to the shaft 27 and to the discharge chutes 23. When the gas in the bell 5 is drawn ofl` for use to such an extent as to lower the gas pressure in the bell 5, the latter descends and as it descends, the top bears on the wheel 39 and tilts the double armed leverl 37 against the -counterweight 38, thereby swinging back the arm 36 and pulling back the rack bar 35. In this movement the rack bar 35 rotates the toothed wheel 30 in the opposite direction from that hereinafter decribed, and the pawls 33 engaging the notches 34, the rotation of the wheel 30, being locked to the shaft 27 by the pawls 33, causes the shaft 27 to revolve and the carbid chutes 23 to be carried around in a circle beneath the plate 19, each chute as it comes beneath the curved port-ion 29 of the plate 19 automatically dumping the carbid into the water, as shown in Fig. 1. This movement continues until the descent of the bell 5 ceases. lVhen the shaft 27 ceases to rotate t-he carbid is no longer delivered to the water.

Mounted on the under side of the cover 3 in any suitable manner a registry device 40, of any well-known form, is preferably employed which is provided with a projection 41 acted upon by the upper end of the bell 5 so that as the bell 5 ascends and bears against the projection 41, the amount of carbid supplied to the water will be registered as well as the pressure of the gas in the bell 5. The generated gas is delivered from the bell 5 through the upper curved end 42 of a pipe 43 projecting up through the bottom of the receptacle and extending out of the same and vertically outside of the receptacle to form a stand pipe 44 having its upper end projecting above the ground. Said stand pipe 44 is connected with a filter 45 which in turn is connected by supply pipe 46 with a building or other place to be supplied with the gas.

In Fig. 6 is shown a utensil for removing the residuum from the receptacle when the same is to be recharged which consists of a bucket 47 having a handle 48.

It will be seen that by means of this invention the generator will be thoroughly protected in the receptacle mounted in the ground and that access to the parts may readily be had through the top by removing the cover. It will further be seen that the carbid may readily be fed to the water in the receptacle by the descent of the bell and that such feed of the carbid will be automatically stopped when the bell ceases to descend and that by means of this construction and arrangement of parts the operation of the generator will be automatic and the gen eration of gas and the supply of carbid will be regular and effective in its operation.

The walls l which are formed of vitrified earthen tile are preferably formed in sections 49, joined together in any suitable manner, and as here shown preferably by the overlapping joints 50.

Having described the invention, I claim:

l. In an apparatus of the kind described for generating acetylene gas, a receptacle, a vertical framework, a carbid hopper shaped receptacle suspended from the upper end of said framework, a bell inclosing said framework and carbid receptacle, a plate mounted-beneath the lower end of said carbid receptacle and having an elevated curved portion, a shaft projecting through the top of the carbid receptacle and having its lower end projecting through said plate, a number of arms on the lower end of said shaft, a tilting carbid delivering chute mounted on each of said arms and having a rearwardly projecting end, said chutes being movable in a circle beneath the lower end of said carbid hopper and permitted to tilt by said elevated portion of the plate, a gear mechanism on the upper end of said shaft, and a counterweighted lever connected with said mechanism and bearing against the under side of the upper end of the bell.
